This Australia Day weekend, Greens Leader Christine Milne is ramping up the campaign for country of origin food labelling to support Australian farmers and workers.

Senator Milne has announced that she will re-introduce the Greens bill for mandatory labelling as soon as parliament returns.

"Australia's farmers and food manufacturers are under pressure. Everyone wants to support our farmers and workers by buying local products but our current labelling is too confusing," said Senator Milne.

The Australian Greens have a $46.5 million plan for teaching kids what they need to know about food including funding up to 800 new school kitchen gardens and ensuring healthy eating and nutrition is part of the national curriculum.

"One of the best things we can do to help our children lead a healthy life is to teach them about food - how to grow it, choose it, buy it, cook it and store it," Greens Leader Senator Christine Milne said.

The Greens' $85 million plan to help farmers bypass the Big Two supermarkets and sell directly to consumers will make it easier to get healthy food, help our farmers get a fair price, and create local jobs.

The Australian Greens today have called on Labor and the Coalition to support changes to food labelling laws in the wake of concerns Simplot could close facilities in both Tasmania and NSW due to falling profits.

"We know consumers want to support Australian farmers and producers but the current food labelling rules are just too confusing," said Senator Peter Whish-Wilson, spokesperson for trade and competition policy.

"A vital step the old parties can take to support our producers and food industry is to back a Greens Bill to change food labelling laws.
